JOHN J. SOMMER, OF NORTH ATTLEB ORO, MASSACHUSETTS.

CHAIN JEWELRY.

To all whom it may concern: I,

Be it known that I, J OIIN J. SOMMER, a citizen of the United States,and a resident of North Attleboro, countyof Bristol, and State ofMassachusetts, have invented certain new and useful Improvements inChain Jewelry, of which the following'is a specification.

My invention relates to'jewelry known to the trade as book-link chains,and consists in the specific construction and arrangement of partsdescribed and claimed, whereby a strong link having the appear ance ofsolidityis formed from sheet metal or flat stock, and whereby thewholechain is rendered substantial an'd complete in appearance and finish ashereinafter more fully set forth.

In the accompanying drawings, Figure 1, is an elevation of one side ofseveral links of my' improved chain, the parts being shown on a scaleapproximately two-thirds larger than is customary in the trades; Fig. 2,is an edge-view of the same; Fig. 3, an elevation of the sideof thelinks opposite to that shown in Fig. 1; Fig. 4, is a view of the outerside of a linlnblank shown on a scale approximately three-fourths largerthan in ordinary practice; Fig. '5, is a view of the inner side of saidlink blank; Fig. 6, a central longitudinal section of two links, onecoupled to the other; Fig. 7, a transverse section of a link, taken uponplane of line 7-7 Fig. 6.

Asordinarily made these chains are comparatively small in size, and areenlarged in the drawings forming'part of this specification forconvenience of illustration. Each link is made of a blank stamped out offlat-stock, the shape-of the blank being clearly shown in Figs. 4 and 5.At one ex-.

' tremity the blank B, is formed with the female coupling tongue f,having the eyelet I hole f, and at the otherextremity the blank isformedwith the male coupling tongue 0, adapted to enter the eyelet f, as shownin Fig; 6. Medially the blank is formed with the transverse openings a,a, on either side of the portion of the blank which constitutes thecoupling bar 7).

blank-adjacent to'the bar I), and openings a, a, are recessed as at e,e, to facilitate the bending and doubling over of the blank upon itselfas shown more particularly in Figs. 6 and 7. The longitudinal edges ofthe blank are upset to form inturned flanges 2', z, the opposed edges ofwhich contact with each otherwhen the blank is bent doubl'eas abovestated, and as clearly shown in Fig. 7,

of the drawings. These side flanges, which may be slightly flared orbeveled as related ent in the actual size of chain than in theaccompanying drawings .which obviously and necessarily renderintermediate spaces more apparent than they really are in actual size ofchain. Fig. 2, gives a fair representation of the result attained inthis respect, although the' coupling means are much more ctmspicuousthan in reality.

The method of coupling the links together 'is shown in Fig. 6,the femaletongue f, be-

ing passed through the holes a, a, and around the coupling bar 6, of thepreceding link blank, and into the space between the' broad fiat sides3, of the link, the coupling tongue 0, being then inserted through theeyelet f", and bent 'over the end of the tongue f, thereby efiectuallyand permanently coupling the parts together in such manner as to admitof necessary articulation between links. 1

The contacting edges of the inturned side flanges 2', i, may besolderedtogether or otherwise unitecl, and the usual finish resorted to,concealing the joints, and imparting an appearance of solidity andsymmetry of structure that adds materially to the at tractiveness andvalue of the chain, while materially strengthening and reinforcing thesame.

What I claim as my invention and desire to secure by Letters Patent is,

A chitin of theoharacter designated, comprising a series of linksarticularly connected, each link consisting of a blank of sheet metalformed with a coupling bar and openings adjacent thereto, withinterlocking tongues for coupling with a preceding link, and withinturned longitudinal edge flanges contacting with each other inthe 10lVitnesser- JAMES E.
